` To all whom it may concern,.- Y

Be it known that LARTHUR CoNsTAN'rIN KREBS, a citizen of the Republic of- France, residing inParis, France, have invented certain new and useful Improvements in Cone- Clutches, of which the following isa specilication. y

`This arrangementhas for its object to pro! duce the drivingof one shaft. by another by means of a cone-clutchwithout there being.

exterior action of these shafts in the axial direction.

In the accompanying drawings, Figures l and 2 are diagrammatic sections of two different embodiments of the invention. Fig. 3 is a longitudinal section of the embodiment shown diagrammatically in Fig. 1.l Fig. 4 is a section on the line't 4 of Fig. 3. Y

The general arrangement shown in Figs. 1 and 2 consists in placing the two cones a. and ZJ so that the one, a, is in 'connectionwith the shaft that is to be driven, the other,`b, free on this shaft, but connectedto the driving-shaft by studs c, which allow b to-move longitudi- ,25,

the cone b in the direction to compress the spring. The driven shaft cannot move under the action of the spring during the unclutching movement, being held by the stop fr.

The motor-shaft m has on it the fly-wheel a), having two projecting driving-studs c,

which engage in holes hushed with steel e in i the periphery of the driving clutching-cone b, which has a covering f of leather. v cone b is fitted onr a sleeve' g, which is free on the driven shaft h. Thesleeve g has collars and grooves which engage in an external sleeve lo, made in two pieces, held together -by a ring Z. A helical spring d bears at one end against the external sleeve, and at the other end againstthe stop fn, which is screwed on the shaft 72.. By the action of the spring cZthe external sleeve pushes the cone b against the driven cone a without moving the latter on its shaft h, since this shaft is subject to wheel of the motor.

l the equal and opposite action of the other sleeve 7c. By pressing the arm r in the direction of the arrow the cone b is moved back. Its sleeve g is quite free and can turn without putting any stress on the collar of the external sleeve 7c. Consequently it cannot transmit-any motion to the shaft 7L though the cone b continues to revolve with the iiy- Thus the unclutching is complete.

Anirnportant feature of my improved clutch and which adapts it especially for clutching a drivingshaft and a driven shaft which are in line with each other is that the studs cf, by reason of the slight play which they necessarily have in the steel bushings e, give a certain iiexibility to the connection, so as to permit a slight deviation of either of the shafts out of its true line, as if they were connected by a laterally-yielding connection.

Having thus described the nature of lthis invention and the best means I know of for `carrying the same into practical eect, I

-between the spring and the friction member b is avoided, and a reciprocal friction member adapted for engagement with said member Zi.

"2. A frictionclutch comprising in combination a driving-shaft and a driven shaft which are in line with each other, a driving Vfriction member connected for rotation with said driving-shaft and loosely mounted on said driven shaft so as to be rotatable and slidable thereon, a driven friction member connected to said driven shaft, a shoulder on said driven shaft, a spring on said driven shaft bearing at one end against said shoulder and at the other end against said driving friction IOO i i'nember to move the same into engagement with said driven friction member to clutch said shafts to each other, and means for moving the same out of engagement with said driven friction member.

3. A friction-clutch comprising in combination a driving-shaft and a driven shaft which are in line withl each other, a friction member connected for rotation with one of said shafts and loosely mounted on the other of said shafts so as to be rotatable and slidable thereon, a reciprocal friction member studs, a driving friction member having holes in which said studs engage to connect saidy member for rotation with said Wheel and to permit longitudinal movement relatively thereto, said driving friction member being loosely mounted on the driven shaft so as to be rotatable and slidable thereon, a driven friction member connected to the driven shaft, a shoulder on said driven shaft, aspring on said driven shaft bearing at one end against said shoulder and at the other end against said driving friction member to move the same into engagement with said driven friction member, and means for moving the same out of engagement with said driven friction member.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

ARTHUR CONSTANTIN KREBS.
